My best is like 113340.53 m without using Cheat Engine for infinite pigs and Mishas, for anything.

Yes, it's possible, simply attach CE to the process running the game.

Infinite wahahas:

Enter your initial number of them in the "Value" section, then click on the First scan, now go back to the game, use one Misha and go back, enter 2 and click on the "Next scan" button. Now, use one Wahaha more, pause and go back, change the value tab to 1 and nextscan it. You should get in the addresses one or two ones, click them down, change their values as you wish, or/and apply them. There you have it - infinite Mishas.

Infinite pigs:

This one is tricky to do, because it's only 2 pigs, after you banged Yuuko *NO PUN INTENDED*. But the routine stays the same, just do this after Hisao hits the ground, when you will get just one pig, search the changed to 1 value, click it down, change the record to anything better than 0 or 1 and apply it. Now, you can bounce infinitely on the ground without losing any speed.
